'The microtome we are most accustomed to is a 'sliding microtome' made by Jung of Heidelburg; it gives excellent results. Recently however Messrs Caldwell and Thelfall have designed an automatic microtome which has been used with success at the Cambridge Morphological Laboratory and promises to effect a great saving of time and trouble in cutting sections (vide p. 471 and Proceedings of the Cambridge Phil. Soc. 1883). A convenient small microtome is one made by Zeiss of Jena (also by the Cambridge Scientific Instrument Company), in which the object is fixed and by means of a finely divided screw raised through a hole in a glass plate, across which a razor held in the hand is pushed. We will briefly describe the method of manipulation for the small microtome, it will be found easily applicable to Jung's sliding microtome.' (434-435)

'Since writing the account of section-cutting on p. 434, we have obtained more experience of the practical workings of Messrs Caldwell and Threlfall's microtome there mentioned. We find that it cuts more accurately and better than any other microtome with which we are acquianted, and can confidently recommend it to investigators and teachers with large classes. In the Cambridge Laboratory, it is driven by a small water engine and will cut at a rate of 500 a minute, without detriment to the sections.' (471)
